To all whom it may concern.

Be 1t known that I, CORNELIUS A.'Fo'LLY,

a citizen ofthe United States, and a resident of ,Boonton, in the ciounty of Morris and State, of New. Jersey, have invented a new and Improved Non-Refillable.- Bottle, of

,,which the following is a full, cle r, a d aotdescriptio I This invention relates to bottle closures and particularly to what is commonly known as a non-refillable bottle, and has for an object the provision of an improved simple,

, strong construction which utilizes the principle of'air displacement in its construction whereby refilling is positively prevented.

Another object in view is to provide a strong construction which has a minimum number of parts which coact for readily forcing of fluid into the bottle after apartial vacuum has been secured therein.

In the accompanying drawing Figure 1 is a longitudinal vertical section through the upper part of a bottle and stop per disclosing an embodiment of the inven' tion.

Fig. 2 is a side view of the structure shown in Fig. 1.

Fig. 3 is a View similar to Fig. 1 except that the parts are substantially inverted.

Fig. 4 is a sectional view through Fig. 1

on line 44.

Fig. 5 is a section through Fig. 1 on line 5-5.

Fig. 6 is a side view of a locking pin embodying certain features of the invention.

Fig. 7 is a vertical sectional view through the cups and float disclosing a slightly modified construction to that shown in Fig. 1.

Referring to the accompanying drawing by numerals, 1 indicates the neck of a bottle, said bottle being of any size orshape. The upper part of the neck is provided with threads 2 which may'beof the ordinary type or what is known as quick-acting threads.

' The threads 2, however, must be provided with notches 3 regardless of the type of thread, said notches being designed to receive the pin 4 whereby the parts are locked against removal by any one. It will be noted that the locking pin 4 co-acts with a locking sleeve 5, said sleeve having a shoulder 6 overlapping the shoulder? of thepor- (1613111 cas1ng-8.- 'The sleeve5 is provided with threads 9 designed'to .coact with'the threads 2 whereby the sleeve 5 "may be screwed downinto position andcause the shoulder 6 to press against shoulder 17 for clamping the casing 8 tightly against the packing washer 10, which washer bears against the upper end of the neck 1. In

forming the sleeve 5 a grooved portion 11 1s provlded arranged in line with the aperture 12 sald groove accommodating the pin 4. It will be noted that the groove 11 em tends only across the threads 9 and that a space 13 is provided above the threads whereby when the pin 4 isforced through aperture 12 into some of the notches 3 the upper ends 14 and 15 of the pin 4 maybe I automatically spread apart, said pin-being of spring material. This will lock the pin against removal by any one and, consequently, as the pin 4 is in the groove 11 and be prevented. The locking is absolute and the parts cannot be broughtto an unlocked position even by an authorized person {so that the only way the sleeve 5 may be removed and also the casing 8 is to break the sleeve 5. I p

The casing 8 is preferably made from porcelain, as it comes in contact with. the fluid, but if desired it could be made from other material. During the construction of the casing 8 the same is provided with guiding beads 16 merging into transverse guiding beads 17, whereby the buckets 18 and 19 are spaced from the walls of the casing continually, as well as the float 20. The lower end of the casing 8 is provided with arecess 21 for accommodating the outer edge and flange 22.01": the trap 23, said trap being provided with a depending portion 24 coming opposite the packing washer 10 and an 19 which rests on this packing when the botnotches 3 any movement of the sleeve 5 will position or' slightly reason of rotated. In this way a lock 13 provided I discharge opening tie is in an upright position. The buckets 18 and 19 may be made of any material, but preferably of porcelain, while the float 20 may be made of any material but for ease of manufacture and for the sake of cheapness it is preferably made from cork, said float acting as means for raising the bucket 19 and pressing the same against the packing member fluid is being forced therein, whereby said fluid cannot pass the bucket 19. In forming the bucket 18 vided with a rounded bottom 27 and beveled or tapering sides 28. This is desirable as it will cause the bucket to press against the float 20 under the action of gravity when the bottle is in a substantially horizontal before it reaches the horizontal position from a vertical position. By this construction of bucket the lower bucket 19 will be held against its seat untll the bottle has been turned to a horizontal or greater than a horizontal position from a verticalposition. The upper end of the easing 8 is provided with a restricted opening 30 having a discharge section 31 and an mwardly extending tubular extension 82 which maybe flush w'th the guiding beads or ribs 17 or may extend below the same as preferred. y

In operation, after the contents has been placed in the bottle, the casing and parts connected therewith are placed in position,

as shown in Fig. 1, and then the sleeve 5 passed thereover and then screwed down until the casing 8 presses tightly against the washer 10, after which the pin has completely passed through the opening the ends 14: and 15 will spread apart by reason of the resilient nature of the pin, whereby the pin cannot be withdrawn even by an authorized person, and as the lower part of the pin is engaging the groove 11 and the threads 2 by the notches 3, the sleeve cannot be which cannot be unlocked. After the. cap has beenplaced in position as just described and it is desired to remove all or some of the contents, all that is necessary is to turn the bottle over completely or to an angle substantiallyas shown in Fig. 3, whereupon the fluid will flow past the buckets 18 and 19 in the space between the beads or corrugations 16 and17 and will eventually pass out the 30. After the bottle has been completely emptied no fluid can be forced therein, nor can there be .any fluid forced therein when the bottle is partially emptied, as the buckets 18 and 19 will prevent the passing of fluid into the bottle.

In case the bottle is inverted and a suctlon pump placed thereon so, as to produce a vacuum in the bottle, said Vacuum may be 26 when the bottle is inverted and V the same is preferably prothe pin at, as shown in detail in Fig. 6, is forced through open-, ing 12. As soon as passageway. If it is attempted to fill the bottle when in a vertical position the bucket 19 acting through gravity, will prevent the passage of fluid, and in case the bottle is attempted to be filled while in a horizontal position the first movement of fluid therein will cause the bucket 18 to tilt over to one side and in the tilting movement will strike the float 20 and force the bucket 19 to its seat, saidmovement being assisted by the flow of fluid.

In Fig. 7 will be seen a slightly modified form of the invention inwhich the bucket 18 coacts with the float 20 in the manner heretofore described while the bucket 38 is provided with a by-pass 34, which may be formed with an enlarged upperend 35, if desired, said by-pass being normally closed by the float 20, which float may from anyimaterial, as for instance, cork. This construction may be used for fluids of any kind, though it is preferably used for comparatively heavy fluids, as for instance, sauces and the like.
